As we're talking about laws;
The Scottish Government has ruled that as of next September I'll need a license to sell Dirks or even Sgian Dubhs with blades longer than 3.5". We don't yet know all of the exact licensing conditions but know that we'll have to verify the age and identity of people buying these, even for export, keep records, maybe increased security, etc.
Of course, the cost and conditions are likely to increase over time so we haven't decided if we'll apply for a license or instead just stop making items covered by the new act.
Annoyingly we could make and sell without restriction the number one instrument used in stabbings, that's right - kitchen knives....
